DMARC Report Received from Verizon: What You Need to Know
February 17, 2025 | 3 min read
Understanding DMARC Reports from Verizon
Verizon, a major telecommunications provider, offers email hosting services that support both personal and business communications. To ensure that emails sent from your Verizon-hosted domain are properly authenticated and protected against threats like phishing and spoofing, DMARC (Domain-based Message Authentication, Reporting & Conformance) plays a crucial role. DMARC reports from Verizon provide valuable insights into how recipient servers handle your emails based on SPF and DKIM checks, helping you secure your domain and improve email deliverability.
Key Components of Verizon DMARC Reports:
1. Source IP Address: Displays the IP address used by Verizon to send your emails. Monitoring this ensures that emails are originating from Verizon’s authorized IP addresses, preventing unauthorized use of your domain.
2. DKIM Alignment Results: Indicates whether the DKIM signature in the email aligns with the domain in the “From” header. Ensuring proper DKIM alignment is essential for passing DMARC checks and maintaining email security.
3. SPF Alignment Results: Verifies whether the sending IP address from Verizon is authorized by your domain’s SPF record to send emails. Proper SPF alignment ensures that only authorized IP addresses can send emails on your domain’s behalf, protecting it from spoofing.
4. Disposition: Provides information on how recipient servers handled your email—whether it was delivered, quarantined, or rejected—based on the DMARC policy you’ve set for your domain.
5. Message Count: Shows the number of emails sent from a particular IP address, helping you monitor email volumes and detect any suspicious or unauthorized email activity.
Automating DMARC Parsing for Verizon
Parsing DMARC XML reports manually from Verizon can be a complex and time-consuming process, especially if you send large volumes of emails. Automating this task with tools like Skysnag simplifies DMARC report management, allowing you to quickly identify and resolve email authentication issues.
– Data Aggregation Across Providers: If you use Verizon alongside other email providers, Skysnag aggregates DMARC reports from all platforms into one unified dashboard. This simplifies managing email authentication across multiple services and ensures full DMARC compliance.
– Visualizing Key Metrics: Skysnag converts raw DMARC XML data from Verizon into visual dashboards that display important metrics like DKIM/SPF pass rates, unauthorized email attempts, and top-sending IPs. This helps you easily identify and address email security issues.
– Automated Incident Response: Skysnag provides real-time alerts when emails sent through Verizon fail DMARC checks (e.g., SPF or DKIM misalignment). These alerts enable you to take immediate corrective action, such as updating DNS settings or blocking suspicious IP addresses, ensuring your email authentication remains secure.
– Forensic Reporting: Some DMARC reports offer forensic data, including full email headers from failed messages. For Verizon users, this information is crucial for diagnosing why certain emails failed DMARC checks and improving overall email security.
Ensuring Proper DMARC Alignment for Verizon
To ensure that emails sent through Verizon pass DMARC checks and are delivered successfully, both DKIM and SPF must align with the domain specified in the “From” header. Misalignment can result in emails being quarantined or rejected by recipient servers. Proper DKIM and SPF alignment is critical to preventing spoofing and improving email deliverability.
Skysnag’s Custom Solutions for Verizon:
– DKIM Key Management: Skysnag ensures that DKIM keys used for Verizon emails are properly aligned and up-to-date. If any misalignments or outdated DKIM keys are detected, Skysnag will notify you, enabling you to resolve the issue quickly and maintain DMARC compliance.
– SPF Flattening: When using multiple services alongside Verizon, your SPF record can become overly complex, exceeding DNS lookup limits. Skysnag automates SPF flattening to optimize your SPF record, ensuring it stays within DNS lookup limits and prevents email authentication failures.
– Policy Recommendations: Based on patterns identified in your Verizon DMARC reports, Skysnag can recommend policy adjustments, such as transitioning from “none” to stricter enforcement modes like “quarantine” or “reject.” This helps protect your domain from phishing and spoofing while ensuring that legitimate emails are delivered securely.
By automating DMARC report parsing and offering tailored solutions for Verizon users, tools like Skysnag help ensure your emails are properly authenticated, securely delivered, and protected from unauthorized use, ultimately enhancing your domain’s reputation and improving email performance.
